Description

A MACHINE FOR FLUSHING PASTA OR MASS Technical Field The present invention refers to a machine used to roll or flatten dough or dough and to configure it in circular discs provided with a non-pressed peripheral edge, preferably used to produce and prepare pizza pies , tarts, cakes, etc. Prior Art Machines and devices designed to spread pasta with rolling pin are known to be used in order to form pizza pies. However, they have two drawbacks: the dough or dough is not flattened or rolled out in the same way as during manual kneading, instead it is pressed, thus giving the dough characteristics that decrease the quality of the final product after baked; the dough sheet does not have an upward projecting edge (which should be evident and more spongy than the remaining part of the dough after baking) and that edge should be manually formed by the pizza cook around the periphery of the dough. the sheet of pasta that has been obtained by the machine. In practice, there is no machine and / or a device that extends or flattes paste into circular discs provided with a peripheral edge, without considering the diameter of the disc and which in any case can provide a peripheral edge in which the paste is not compresses or cracks.

Description of the Invention The objective of the present invention is to provide a suitable machine for preparing pasta discs used to make pizza pies, which allows making discs of different diameters, always having a peripheral edge and with characteristics, such as sponge paste, identical to those of pizza pies prepared manually by expert pizzas cooks. The present machine also allows to prepare disc or paste without peripheral border, in order to manufacture other characteristic products such as the so-called "piadina romagnola", the "tigella montara", etc. According to the present invention, this object is obtained by a device of the aforementioned kind, characterized in that it compresses two discs or plates, a lower one which is rotated by a motor on whose upper face spirals are added or formed and a plate or upper disc that does not rotate and that is concentric and slides mutually axially, each one more inwards with respect to the preceding one, or by radial sectors that engage a central part. The upper plate or disc is lowered parallel to a lower one while the latter is rotated. As the two plates approach each other, the mass of the paste placed between the plates, at its center, gradually flattens out from the center to the outside and a peripheral edge formed by the paste that has not yet been flattened, will always be I presented. The amount of paste that has been interposed between the plates or discs, and the stoppage of the decrease of the upper plate at an appropriate time, will establish the size of the diameter of the disc and its thickness.

In the different figures, the same alphanumeric reference signs denote the same parts or elements. BEST MODE FOR CARRYING OUT THE INVENTION In Figures 1 to 13, a first embodiment of a machine is shown for rolling or flattening dough, in order to prepare circular discs of variable thickness paste provided not with a peripheral edge, the machine including the improvements of the present invention. With reference to Figures 1 to 8, the reference number 1 denotes the bed of the machine inside which the radio-motor 2 is located and fixed, said motor being used to rotate the lower plate 3, including one or more spirals in projection 4, which are composed of material added or obtained directly from the disk. A sheet 5, of a suitable kind, adheres to the spirals and is fixed to the bed 1. In bed 1, two vertical guide rods 6,7 are fixed on which the support 8 can slide, being driven by a linear actuator 9. The support 8 supports the upper plate 10, which mainly comprises, according to a first mode: a cover 11 fixed to the support 8; - a central plate 12 provided with one or more supports 13 that support the circular rings 14, 15, 16, 17 by means of screws 18 which are screwed on them and whose head 18 / a slides inside the seats obtained in the supports 13; the torsion springs in the form of coil springs 19 acting between the bottom of said seat and the head of the screws 18, forcing the rings 14, 15, 16, 17 to abut the bottom surface of said supports 13. The rings 14 , 15, 16, 17 are concentric to the central plate 12 and slide axially one over the other. The supports 13 are in contact with the cover 11 and are fixed thereto. On each ring 14, 15, 16, 17 three sectors are obtained (projection) 14 / a, 15 / a, 16 / a, 17 / aq * that start forming an inclination 14 / b, 15 / b, 16 / b, 17 / b, acting as a cam or eccentric (see also Figures 5.6). On the cover 11, three adjustable thin bearing rods are mounted, which will be brought into contact with three bearing points provided on the bed 1 when the actuator 9 decreases the support 8. The adjustment of said thin bearing rods establishes the distance to which the central plate 12 with respect to the spiral 4 of the lower plate or disk is stopped, and therefore also the final thickness of the disk of the dough or mass to be obtained. Centrally, in a suitable hub provided on the cover 11, a small spindle 21 (Figure 8) is inserted on whose upper end a toothed pinion 22 associated with a gear 23 driven in both directions is formed (or mounted) by a linear oleodynamic actuator 24 fixed to the cover 11. Three arms 25 (Figure 8) are interposed between the inner surface of the cover 11 and the circular rings 14, 15, 16, 17, said arms being connected to a small block 26 which supports them, this block being fixed to the spindle 21. On each arm 25. six free wheels (or radial bearings) are inserted, two of them, denoted by 27 and 28, are in contact with the inner plane of the cover 11, while the others can interact only with the sectors similar to cams 14 / b, 15 / b, 16 / b, 17 / b, when, by means of the linear actuator 24, the small spindle 21 is rotated in the direction of the arrow F2, together with the corresponding wheel support arms 25. Therefore, c A three-wheeled group (one for each arm 25) acts on the cams of the same ring, which decreases until it is flush with the small center plate 12. In the rings, the cam-like sectors are arranged in sequence so that each ring begins to decrease when the preceding one is already leveled with the small central plate 12. The two small wheels 27, 28 which are carried on the cover 11, on its internal part, prevent the arms 25 from bending upwards due to the impulse transmitted to the wheels interacting with the cam-like sectors. A disc made of teflon-coated fabric 30 can cover both the small central plate and the circular rings. If the small central plate and the circular rings are manufactured with great precision and with a suitable material for food products, it is possible to avoid the use of the cloth 30. Therefore, when the plates or disks are separated from each other, each ring Circular acts as a means of separation in the sense in which it helps separate the paste or mass from the adjacent ring (if they adhere to it). In the rest position, the small wheels are not in contact with the cam-like sectors (Figure 7). The operation of the device is as follows: after turning on the radio-motor 2 by means of an appropriate oloodynamic control unit (not shown) that may or may not be incorporated in the machine, the actuator 9 which lowers the support is operated.; when the bearing rods 20 are carried in the bed 1 and the downward pulse is stopped, the pressure inside the oleodynamic circuit is increased; a sequence valve which has been calibrated to a pre-set value, opens to itself and operates the actuator 24 which rotates the spindle 21, causing the successive descent of the rings 14, 15, 16, 17. It is obvious that the descent can be stopped at any time, that is: immediately after the small bearing rods 20 touch the bed; after lowering the first ring 14; and so on. Figures 9 to 12 show the manufacturing cycle of the pasta discs: - when the machine is not operating, or when the radio-engine 2 and the control unit or the dynamic unit are switched on, a piece of pasta 29 is placed in the bottom plate center (Figure 9); the actuator 9 is operated. When the small bearing rods 20 are stopped on the bed 1, the pulp 29 has flattened as shown in Figure 10, and forms a central zone (whose diameter is equal to the diameter of the small central plate 12) already having the desired final thickness "S" which is established by the adjustment of the small bearing rods 2, and a large edge 29 / a which is composed of the mass of the excess paste; - when the sequence valve igniting the actuator 24 is released, the first ring 14 descends (Figure 11) and successively all the others until the final situation is reached described in Figure 12, where the pasta disk has an edge corresponding small end 29 / b. By varying the amount of paste 29 and the thickness "S", it is possible to obtain: pasta discs, comprising an edge, of how many different diameter sizes as the number of rings are increased by one. In the illustrated example, we have five discs of different diameter, to make pies or pzza cakes; the disks of different size of diameter but without edge (Figure 13), for the preparation of cakes, "tigelle montanare", "piadine", etc. The modality, as shown and described before, is not the only one possible. Accordingly, a machine for roller flattening or rolling of the paste according to the present invention can not be of the kind comprising axially slidable circular concentric rings, but of a kind that includes hinged sectors (Figures 14 to 17), where 12 / a denotes the small central plate, which in the present case has a hexagonal shape and is provided with six supports 13 to be fixed to the cover 11. They are connected to the small central plate 12 / a, through the hinges 30 , a plurality of sectors 31 which are raised peripherally by means of tension springs 32 acting between the hooks 33, mounted on or integral with the sectors 31, and hooks 34, which are fixed to, or integral with the supports 13. In each sector 31, in a manner similar to that performed by rings 14, 15, 16, 17 of the previously described embodiment, a cam 35 / a, 35 / b is added or integrally formed with the sector, on which it acts one wheel l ibre 36, while a second small wheel 28, which also rotates freely, rolls the bearing on the inner surface of the cover 11, as in the previous embodiment.

The small wheels 28 and 36 are mounted freely on the bolts 25, which are assembled and driven by means of the actuator 24 and the gear 23, in exactly the same way as in the mode employing concentric circular rings, in order to descend gradually Sectors 31, when the paste should be flattened starting from the center towards the periphery. As can be seen, both modalities are similar; in the modality that employs pivot sectors, a number may be different to six; the thickness of the paste is always determined by adjusting the small bearing rods 20, and the paste is gradually flattened from the center towards the periphery as the sectors descend by driving the small wheels on the cam-like sectors . Substantially, the operation of the machine is the same as that already described for the modality that employs circular concentric rings. In both modalities, the disc 3 carrying the spirals 4 plays a fundamental role, influencing the flattening of the paste and the execution time. The number of times given to the disc or plate 3 is determined by the number of spirals 4 that are present on your face, and by the ownership of the mixture that makes up the pasta. If necessary, the radio-motor 2 can be replaced by a step-change speed gear or by a radio-motor combined with a shift gear with many speed levels. Industrial Applicability The two modalities that have been shown and described refer to the realization of machines used in pizzerias, restaurants, bars, etc. The principles of the operation illustrated by them, ie a lower rotation plate provided with spirals that form projections, an upper plate formed by rings or concentric sectors, can be used to realize automatic plants (or lines) for industrial production of pies for pizza (for example). An automatic line is an automated multiple station transfer machine where the lower part of each station is provided with a disk or motor-driven plate 3 carrying spirals 4; At the top of each station there is a plate or disk whose small central plate 12 or 12 / a has a diameter size that becomes longer and longer according to the desired number of passages or stations that. As stated earlier, divide the cycle to flatten the pasta. The advantages with respect to the present industrial production lines of pizza cakes are the following: the production and heating of the pasta are as low as possible since the flattening or roll spread of the pasta is divided into more steps; The period of each cycle is reduced to the time required for a single step, with an obvious obvious increase in productivity. As will be obvious from the description given before two preferred embodiments, the invention is not limited to the mentioned example, which has been presented for illustrative purposes only. It should be understood that other steps, example, constituent parts and methods of operation will originate spontaneously in the mind of one skilled in the art after a careful reading of the present description, even if this is not considered to be related to the scope of the invention. since the last of claims in the present.
